[4.5.1]: URL function params argument not respecting {id}

[KatieMFritz]

What happened?

Description

I'm using the following code to reload a page with the ID of a newly created "lead" entry from an entry form:

redirectInput(url(baseUrl, 'lead_id={id}')

It was working originally, but after upgrading to Craft 4.5, the params argument is no longer replacing {id} with the entry ID when the form gets submitted. Instead of ?lead_id={id}, the generated URL includes ?lead_id=%7Bid%7D.

It works if I only use the path argument: redirectInput(url("#{baseUrl}?lead_id={id}")) or if I use regular Twig template interpolation: redirectInput(url(baseUrl, "lead_id=#{formId}")).

However, those options don't work for me, because my baseUrl variable has an anchor in it. If I use the params argument, the anchor gets bumped to the end and everything works, but if I only use the path argument, the params get ignored because they come after the anchor. I can split up my anchor to a separate variable and concatenate everything, but I think this is a bug.

Side note: I don't know what that type of system-generated variable is actually called: {id}. Is it a token?

Steps to reproduce

1. Create an entry form.
2. For the redirect URL, use the URL function. Include {id} somewhere in the params argument.
3. Load the page and inspect the generated redirect URL.

Expected behavior

We should see {id} in the URL params for the redirect URL. Submitting the form should replace {id} with the actual ID of the newly created entry in the new URL.

Actual behavior

The redirect URL params include ?%7Bid%7D, even after submitting the form.
